Specification of Letters Patent. Application filed August 7,1905 Serial No. 273,047.
Patented Feb. '13, ieee.
To all' whom, tm/ay concern:
Be it known that I, FRANK Dn COLIGNY, a the chamber C l citizen of the United States, residing at Chi- Transmission Device,
cago, in the county of Cook and State of Illinois, have invented a new and useful Power-- lof which the following 1s a specification.
y invention relatesto improvements in Athe construction of apparatus which is interple, compact,
A-Hinged at f isaswingiiilT posed the like to vary' the imparted power and speed by controlling the circulation or degree of sl`p of a confined body of practically incompressible fluid' through which the driving force is transmitted.
My object is to provide a power and speed transmitting device of the above class of simand generally'impi'oved eonstruction,` adapting it more especially for use upon automobiles.
In the drawings I show a simple embodiment of my invention as l prefer in a general way to construct it for use in automobiles to vary the speed and power transmitted from a power-shaft running at regular speed to a propellenshaft.
Referring to the drawin s, Figure 1 is a sectional side elevation of t edevic'e; Fig. 2, a section through the device in a plan parallel with Fig. 1 and Fig. 3 an enlarged crosssection taken on line 3 in Fig. 1.
A is the power or driving shaft, and'B the propeller or driven shaft. `The latter carries at its end a cylinder C, having an inner chamber C', nearly surrounded by a wall a. Ex# tending around the Wall a is an outer chamber C2, which has a'wall b at one end 'and opens at its oppositeend through port c into the chamber C. Extending across the chamber C2 in the position shown is a hollow wall or abutment D, having ports d through it and forming the casing of a slide-valve E, provided with ports adapted in the sliding of the valve to open and close the ports d. l Between the walls b vD is a chamber F, opening through a port .e into yment G of theexaotfwidt vofthe chamberC i and pressed, as'shown, by agspring g.
I'. shaft B., passing thro The,` driving sha-a A 'a in hawaii its one ,wall of the: casing end in 'a bearinghsocket iin the opposite ywall between'driving and driven shafts or the f, chambery 0.. f ldefleotor .on abut f righe stuiingvbox 7L in l fixed upon the shaft A. The rim, of the wheel H is formed with anannular bearing recess H,in which its'the inner'periphery of a rotary ring or wheel I, having aflanged rim portion l.
osite edges of the riiii I slidein deflector G. The valve E has 'a stem E passing through a stufling-box c in the wall ofthecasing, and
connected vwith the said 'st ein'is lever fu'l-v cruined at Z and having a'bifurcatedeiid l* loosely embracing a sliding c'ollaifgKl on the shaftB. .l 1
K is a lever mounted ina suitablel sup port- The nearlyannular and cireuiny ferential wall a is provided with a lining a of leather or the like, terminating or `cutaway The .side wells near the with annular strips of leather 'or the like t the linings a2; and. the fat-'e or the rim is maintained by the eccentric in rolling contact with the lining'a vand yielding' ofthe same. lllidway Awallsy t).
is a wheel H,ec`ccntrically and having a bifurcated end also loosely bracing the collar K, as indicated. fl The chai'nber. C2 is filled withoil or other suitable incompressible fluid and forms,
the space in the chamber-G bletweenthe'rim I and lining a', as wellasfthechamber F. 7
@wing to the diiculty that there maybe of .8 i iii e'ffeet, an oil-'storage chamber, theloil also filling maintaining an oil-tight' joint lbetween the rim l and linings a2, the chamber Cwithin the rim l may also be fillcdfwith oil-,1.whiclifis byathe stuffing-l)offsl h. In the end of the vcliainberl,i near the;
prevented from escaping Wall l), I provide a plunger-pistonli,backed v by aspring L. In filling the device witli olli pressure may be eii'iployed to iiiove`tl1e'[ is` ton L against the resistance o f the vspriiigsL, whereby in the event of "niorejor lesssliglit leakage of oil the piston will advance tocoinerate .tokeep the pil Y ensate therefor and o in the chambers at all times under slight pressure.4 f
In the rotation ofthe prime shaftAv thewcentric isrotatedthereby canse, ii g1 the .wheelf' v`l to grotateI lthereon endroit roo uponL the inner, zperiplierypr lipin a" ot" `the I chamberl C. The direction .o'l te angular,-l i
movement ofthe .wheel I is indicated "by-the,`
and jonrnaled at its. .t arrowin Fig., 2.. n The ports tffinith'f'g'eli its plete the oil between the ment D afford when o 'en free communication between the chamhersf C2. Therefore when the valve E is 1go" enejd the wheel I as it rolls around forces'theoil entering at -c out through the opening'cf'ft'o the chamber F and thence back to the. chamber C2. The chamber F, ports d, and chamber C2 form a circulating-conduit for the oil between the ports e c. During this free circulation of the oil ractically no working pressure is exerted by it against the abutment D, and the casing C and ropeller-shaft will not be rotated.. The yiel ing deflector G being in constant contactwith the rim I deflects all the oil forced by the wheel into the chamber F. Gradual closure of the valve E reduces the slip of the oil through the ports of the abutment D and causes gradually-increasing ressure to be exerted against the casing at the abutinentD -to rotate it and the propeller-shaft; Comclosing of the valve E, which shuts H circulation of the oil, causes that portion of line of contact of the rimwith they wall a', on the one hand, and the yielding abutment G and fixed abutment D, on the other hand, to form an unyielding filler,
whereby the propeller-shaft will be rotated at the same speed as the power-shaft. Thusunder a given resistance the com arative velocity ofthe propeller-shaft will piend upon the adjustment .of the valve effected through the lever l and collar-K by adjustment of the lever K The wheel I is, in effect, a pump and works without material frictional resistance in rolling upon the surface a and as all the parts are in an oil-bath frictional resistancebetweenmoving surfaces is reduced to aminimum.
Naturally my improved power-transmission devicewould operate were the shaft B the power-shaft and A the propeller-shaft. The cylindrical casing C would be made in sections and suitable means provided for fastening the sections securely together, with oiltight Joints between them. The valve which governs the slip of oil and its operating means should be so constructed asto -be under per-, fect control of the attendant, whereby the lchanges in relative speed transmitted to the propeller-shaft may .be quickly and accu- 4 rately accomplished..
